Abstract :
Noise parameter measurements of six candidate transistors for a Square Kilometer Array (SKA) low-noise amplifier (LNA) are presented. They provide reliable data in the frequency range where some low-noise transistors are inadequately characterized. The results of these measurements inform the design of an LNA for SKA1-Survey Band 2 with measured minimum noise temperature of 21 K.
